To a/ZZ whom t may concern:

'Be it known that we, AUGUST GEAEMIGER, a citizen of the Republic ofSwitzerland,and a resident of Cheetham, and WlLLIAM THOMAS VHITEHEAD,asubject of the Queen of Great Britain, and a resident of Radcliffe,Manchester, in the county of Lancaster, England, have invented new anduseful improvements in machines for dyeing, bleaching, and otherro wisetreating yarn in cop or other compact form, of which the following is aspecification.

The invention has been patented in England to ourselves and others, No.9,692, dated i5 June 12, 1889.

Our invention relates to improvements in machines for dyeing, bleachingor otherwise treating yarn in cop or other compact form and is ofgeneral applicability to machines zo in which an intermittent rotary copcarrier in conjunction With'a carrier body is employed in a liquor tank,and in Which the cops to be dyed or otherwise treated are placed onperforated injection tubes or spindles and the liquor is drawn or forcedthrough the same by suitable means; and the objects of our improvementsare, irst, to reduce fric tion between the cop carrier and carrier bod yand to increase the capacity-of the machine; 3o second, to provide means'whereby the liquor left in the cops from boiling or mordanting can beextracted; third, to separate the air and liquor extracted from the copsby the preliminary exhaustion chamber so as to prevent the liquor fromentering the air pu'mp and'to effect the return of the same into thetank free of air; fourth, to provide means whereby the machiue,on beingset in motion by the attendant, automatically opens the 4o vacuum valvein connection with the preliminary exhaustion chamber and air pump,closes the same and stops the machine to permit the substitution anddesired treatment of the cops; fifth, to provide means whereby theliquor is automatically supplied to the tank in certain quantitiesaccording to the number or weight of cops to be treated. We attain theseobjects by the mechanism illustrated in the accompanying four sheets of5o drawings, in which Figure l, Sheet I., is a vertical section throughA-B Fig. 3, Sheet Il. Fig. lX is a detached side and front View ofone ofthe cams on the cop carrier operating the lever arm in connection withthe vacuum valve mechanism; Fig. 2, a side View of the vacuum valvedetached and Fig. 3, Sheet II., a plan partly in section ot' a machineWith a double disk cop carrier. Fig. 4, Sheet III., is a section throughC-D Fig. 5, Sheet IV., and the 6o iat-ter a side view with liquor tankin section, and Fig. 6, Sheet IV, a longitudinal section through E-FFig. 4, Sheet III., of a Vmachine with a cylindrical cop carrier.

Referring to Figs. l, 2 and 3, Sheets I and II, a is the liquor tank, b,b the cop carrier, c the carrier body, d the cop carrier axis, e theliquor pump of the machine.

In the tank a is employed a cop carrier, consisting of two disks b, b',suitably fixed on the axis CZ mounted in bearings a and intermittentlyrotated by means of spur wheel gearingf,f,f2, shafts fS and f4 andclutch f5, 75-

from the driving shaft f6 through chain f7,

sprocket wheels f8 and ft. In conjunction with the said two carrierdisks 19,5, a central stationary carrier body c, bolted to the liquortank @,is ground or by means of rubber rings 8o c fitted air tightbetween/the inner faces of the disks b, b. The outer faces of thecarrier disksb, b are respectivelyA formed with four cop tube hole ornipple groups g', g2, g3, and g4, Which serve to receive the perforatedinjection tubes g on which the cops g5 to be treated are placed.

The carrier body c is formed with four chambers 71.', h2, h3, h4,.whichon the intermittent rotation of the cop carrier b,b,come suc- 9ocessively into communication with each of the four groups of cop lubeholes or nipples g', g2, g3, and g4, so as to permit in chamber hsubstitution and liquor (from boiling or mordanting) extraction,chambers h2 and h3, 95 saturation and impregnation, and chamber h4liquor extraction of the cops.

To the top of the carrier body c is connected a pipe t', which is inconnection With a pump and communicates with the chamber h, by Ioo meansof which the liquor left in the cops from boiling or mordanting, (whichheretofore had to be recovered) can be removed in the same machine inwhich they are dyed, the chamber h thus serving as a primary liquorexhaustion chamber. The carrier body c, below the liquor level in thetank a, is formed with a cavity lo, having two ports la', 7a2 leadin grespectively to the saturation and impregnation chambers h2 and h3 andthe pipe lconnected thereto leading to the liquor pump e so as tosubject four cop groups silnultaneously to saturation and impregnation,the liquorbeing returned into the tank a by the pump e through the pipel.

Between the saturation and impregnation chamber h3 and the liquorextraction chamber h4, an inlet pipe m connected to a pump, not shown,is fitted thereto, which communicates wit-h a port m leadingpto theliquor extraction chamber h4.

Between the primary liquor extraction chamber 72, and the saturation andimpregnation chamber h2, the preliminary or air exhaustion chamber hhaving ports n, is formed, which are equal in number to and incommunication with the circular rows of cop tube holes or nipples in thecarrier disks b, b. To the said preliminary or airexhaustion chamber h,is connected an inlet pipe n', n2 furnished with a tap 'n3 leading to anair pump, not shown,

whichv tap n3 serves to cut off .the respective connection as desiredfor certain colors. Into this pipe u and n2 we insert an air and liquorseparator, consisting of a cylinder or casing o provided at the top andbottom respectively with air and liquor valves 0 and 02 formed on therod oB and held against their seatings by means of a spring 04. Thesevalves o', o2 are automatically opened, the moment before thepreliminary extraction of liquor or air exhaustion from the cops takesplace, by means of one or more cams p fixed to the carrier disk boperating a bell crank lever p connected by means of a rod p2 to theforked lever q pivoted to the cylinder or casing o and embracing thevalve rod 08.

The side of the cylinder or casing o near the tap n3 of the preliminaryexhaustion chamber h, is furnished with a chamber q which is incommunication therewith and the pipo n and furnished with a perforateddivision plate q2, preferably concave, against which the air on rushingfrom the preliminary exhaustion chamber h strikes, so as to cause anyliquor which it may contain to separate therefrom and descend into'thelower part and the air to ascend into the upper part of the saidcylinder 0, from which the air is permitted to escape, and the liquorreturned into the tank a on the valves o', o2 being opened as aforesaid.

The pipe n2 between the cylinder or casing o is provided with the vacuumvalve 'n4 by means of which communication is established and cut off asrequired between the air pump and preliminary extractor 71.,automatically as follows: In connection with the clutch f5 a shippingrod fr is employed which when pushed forward by the attendant throws theclutch f5 in gear and sets the machine in mo'- tion, the part of theclutch f5 which otherwise revolves loosely on the shaft f3 being formedwith a sprocket wheel f9 to which motion is transmitted from thesprocket wheel f8 on the shaft f6 by means of the chain f7.

The shipping rod r is furnished on its upper side with a projection frbearing against a lever r2 suspended from the casing of the vacuum valven4 and'bearing against the stem of the latter. Below the shipping rodris positioned alever arm t pivoted to a bracket r3, bolted to the' tanka, which lever arm t, is under the influence of a spring t Fig.` 3 andoperated upon intermittently by four cams 152 which operate respectivelyin connection with each cop group g, g2, g3, g4. When the carrier disksb, b are at rest, the vacuum valve n4 is closed andthe free end of theleverarm t, on the point of the cam t2 belonging to the cop group nextthereto, while a projection r4, provided on' the under side of theshipping rod r, bears against the front edge of the lever arm t.

When it is desired to commence the rotation of the carrier disks b, b',the free end of the shipping rod r is raised a little, so as to free thelever armtfrom the projection r4 and afterward pushed forward causingthe projection 'r' to depress the lever r2 and the latter the stem ofthe vacuum valve n4 thus opening the valve 'n4 and the shipping rod r atthe same time throws the clutch f5 in gear. The free end of the leverarm tis then caused to move down the incline of the respective cam t2toward the disk Z), which causes the projection r4 to leave the upperside of the lever arm t, drop and position itself again against thefront edge of the latter. During the rotation of the carrier disks b b',the vacuum valve n4 remains open until one of the series of cop groupshas passed the preliminary exhaustion chamber h. The cam t2 of the nextcop group then comes into contact with the arm t, moves it outward andcauses the latter to draw with it the shipping rod rand thus close thevacuum valve n4, throw the clutch f5 out of gear and thereby stop themachine.

The liquor in the tank a is automatically replenished by means of acharging vessel uV which is in communication with the same, by means ofthe pipe u and with a liquor reservoir not shown, by means of the pipeu2. The charging vessel u at its lower extremity is formed with a portus which is in communication with a two way tap o having attached to itsspindle a weighted lever o and slot le. ver o2 the latter beingconnected to a sliding rod o3 which is acted upon by one or more camspfixed to the cop carrier disk b and establishes communication betweenthe charging vessel u and the liquor tank a.. The cam p may be vmadeadjustable in length so as to retain the communication, between theliquor tank a and the charging vessel u, open any desired period, thussupplying more or IOO IIO

less liquor to the tank a as may be required for' the number or weightof cops to be treated and to keep the liquor in the tank a always at thesame level. When the cam p leaves the rod o3 the weighted lever o turnsthe tap t; and establishes communication between the liquor reservoirand the charging Vessel u, which latter is formed at the top with an airhole s and ball valve s which floats in a cage s2 on the liquor andcloses the air hole s when the charging vessel u is full.

In order to diminish friction and insure always a good joint between thecop carrier b and its bodyc in a cylindrical machine, see Figs. 4, 5,and 6, Sheets III and IV, we form the carrier body c so as to constituteone end of the cop carrier b, against which the latter rotates, in lieuof inside the same. This carrier body c is formed with segmentalchambers h, h2, h3, h4 for effecting substitution, preliminaryextraction, saturation, impregnation and liquor extraction of copssimilar as hereinbefore described, each chamber being respectively incommunication with the conduits n', k2, m.

In lieu of forming the cop tube holes or nipples in the cop carrier bingroups, we form the same in rows, at equal distances apart, all roundthe periphery of the cop carrier b, a separate segmental cavity w beingformed in the carrier body c for each row instead of for a seriesthereof, which greatlyincreases the capacity of the machine and causesthe cops to be treated more effectually and uniformly.

The cop carrier b and its body c are suitably xed onto the axis d vandmade adjustable thereon against each other by means of nuts d and toinsure an air tight t between the same, the respective surfaces areground together or furnished with rubber rings. l

Referring more particularly to Figs. l and 2, the operation of themachine is as follows: After the tank has been supplied with liquor, andassuming the nipple groups g', g2, g3,

` g4, on the carrier b, b are positioned respectively opposite thechambers Ik', h2, h3, h4, in the carrier body c, the nipple groups g aresupplied with cops g5 previously mordanted, and the superfluous mordantextracted from the respective cops g5 by means of a suction pump (notshown) and the pipe t' connected thereto and the chamber h', whichlatter then communicates with the nipple and cop groups g. After theextraction of the mordant, as described, the cop carrier l), b', is setin rotation, by pushing the lever o* forward which throws in gear theclutch f5. Power is transmitted through the chain f7, wheels fifi andgearsf, f', to the disks b and b', until the cam t2 of the nipple andcop groups g', comes into contact with and moves the lever t and thelatter the shipping rod r outward, `so as to throw the clutch f5 out ofgear and thus limit the rotation of the cop carrier b, b lto aquarter ofa revolution. At the commencement ofthe rotation of the cop carrier b, bthe valve n, which when the machine is at rest is closed, is openedthrough the mediums r', r2 and thereby communication established, by wayof tap n3, pipes n', 'n2 and vessel 0, between the vacuum pump (notshown) and the preliminary extraction chamber' h. During this firstquarter of a revolution of the cop carrier b, b', each radial row of itsperforations is successivelybrought in communication with the ports 'nleading to the preliminary exhaustion chamberh and thus the nipple andcop groups g', fora short period subjected to the action of a vacuumpump (not shown) for the purpose of emptying the same of air previous tobeing saturated and impregnated. On the completion of the first quarterof a revolution of the cop carrier b, b which takes place automaticallyas described,its nipple groups g2, Will be positioned opposite themordant eX- traction chamber 7L and its nipple and cop groups g oppositethe saturation and impregnation chamber h2.' The nipple groups g2 arethen supplied with mordanted cops g5 and the superfluous mordantextracted therefrom as described, while the cops g5 of the nipple groupg are subjected to the action of the liquor pump e, which draws theliquor from the tank a, through the same into the saturation andimpregnation chamber h2, and through port 7s', cavity k, pipes Z and Zback into the tank 0,. After a sufficient period the cop carrier b, b isrotated for a second quarter of a revolution during which the cops g5 ofthe nipple groups g2 are subjected to the action of the Vacuum pump (notshown) in the manner as hereinbefore described. On the completion of thesecond quarter of a revolution of the cop carrier b, b the nipple groupsg4 and nipple and cop groups g2 and g are respectively positionedopposite the mordant extraction chamber h, saturation and impregnationchambers h2 and h3. The nipple groups g3 are then supplied withmordanted cops g5 and the superfluous mordant extracted therefrom, whilethe cops g5 of the nipple groups g2 and g are subjected to the action ofthe liquor pump c, as previously described, thecops g5 of the nipplegroups g' thus receiving a second saturation and impregnation. After asecond period the rotation of the cop carrier b, b is continued for athird quarter of a revolution, during which the cops g5 of the nipplegroups g4 are subjected to the action of the vacuum pump (not shown) inthe manner described. On the completion of the third quarter of arevolution of the cop carrier l), b the nipple groups g3 and nipple andcop groups g4, g2 and g are .respectively positioned opposite themordant extraction chamber h', saturation and impregnation chambers h2and h3, and dye liquor extraction chamber h4. The nipple groups g3 arethen supplied with mordanted cops g5 and the superfluous mordantextracted therefrom, while the cops g5 of the nipple groups g4 and q2are subjected to the action of the liquor pump e, as previouslydescribed, the cops g5 of' the IOO nipple groups g2 thus receiving asecond saturation and impregnation. The cops g5 of the 'nipplegroups gin the meantime are subjected to the action of a suction pump (notshown), which is in communication with the chamber h4 by means ofthepipe m and port m', for the purpose of .extracting therefrom thesuperfluous dye,'which completes the dyeing of the cop groups g. After athird period, the rotation of the cop carrier 19,5 is continued for theremaining quarter of a revolution, f during which the cops g5 of thenipple group g'3 are subjected to the action of the vacuum pump (notshown) in the manner described. On the completion of the fourth quarterof a revolution of the cop carrier b, b', the nipple and cop groups ghave arrived at their starting poi-nt, viz., the mordant extractionchamber h', where the dyed cops g5, are substituted for mordanted ones,While the nipple and cop groups g3, g4 and g2 are respectivelypositioned opposite the saturation and impregnation chambers h2 and h3and dye extraction chamber h4, and the cops g thereof are subjected tothe action of pumps as hereinbefore described.
